When motor start to rotate, I2C signal is cut off.


I am studying I2C between two arduino dues.
When motor started to rotate, signal was cut off.
I used capacitor, 2.2K resistors but it still doesn’t work.

please help me.

maybe your motor draw too much power.

How is your motor controlled and powered?

Thank you for your answer.

I used 12V DC motor and it powered by 11V battery.

Motor controlled by Motor Control Driver Module for arduino.
please refer to link below.

Please post your code and use code tags (the # button) so it looks like this

It may be possible that there is a conflict between the resources producing the I2C signals and the motor control signals.
